'4 Claims. (or. -45) The main object of this invention is the provision of a vacuum cabinet in which mops are adapted to be shaken, the cabinet havirig a motor therein which creates a suction to absorb the ,5 loosened dust, the motor being reversible through an arc of 180 degrees so that the same may serve as a blower or fan.

The above and other objects will become apparent in the description below in which charlu acters of reference. refer to like-named parts in the accompanying drawing.

Referring briefly to the drawing, Figure 1 is perspective view of the cabinet.

Figure 2 is a cross-sectional view taken on the Figure 3 is a cross-sectionalview taken on the line 33 of Figure 2.

Referring in detail to the drawing, the numeral Iii represents a cabinet which may, however,.be of :30 any other suitable shape or form than that shown,

the latter serving for the purposes of illustration only. Near the top of the cabinet iii a horizontal screen 12 rests upon a peripheral ledge Hg, defining a compartment I3 between the screen 12 and the roof of the' cabinet. In the front wall It, an opening isfiformed into the compartment J3, and

a door 15 is mounted therein. Similar openings Iii and I! are formed in the sidewalls of the cabinet on the samelevel as the opening IS. The

30 openings Iii and are covered with a porous or -net-like cloth which will permit free access of air or wind therethrough, and likewise the door i5 has opening within its frame which is likewisej overed.

35 At fa: distance below the screen 12 an electric motor I 8 is supported ona shelf '18, the shaft of the motor extending for a distance beyond the motor frame. 'A housing 2i is supported in the opposite wall of the cabinet and has a horizontal 4U bore in axial alignment with the motor shaft 20,

in which a second shaft 22 is rotatably mounted.

, 1 By means of a set screw 23 a frame 24 is locked on the end of the shaft 22, the sleeve. 24a also being in the same axial alignment. At opposite 45 sides of the frame 24, and also in axial-alignment with the motor shaft 20, are respectively an open- .ing through; which the shaft "passes into the frame and in which the motor shaft is rotatable,

1 and a socket 25 in which the end of the motor coshaft is rotatabiy supported. Within the frame i a bevel gear 26 is rigid .on the motor shaft "'40, and this bevel gear is in mesh with a horizontal bevel gear 2|--rigid on the lower end of a fan shaft 28 which projects vertically upward through us an'opening in the top of the-frame". A fan or screen I 2.

blower 23 is rigid on the upper end of the shaft 28, and lies normally, when the device is ready for use to suck down the'dust shaken from a mop,

inhorizontal position on a level just below the 6 The outer extremity 30 of the shaft 22 is reduced and projects through the front wall II, and

has locked thereon a lever or handle 3i. A disc or plate 32, which is integral with the housing 2|,

lies .fiush against the outside of the wall I! and 10,

is provided with a pair of peripheral recesses 33 and 34, one vertically above the other. On the extremity of the lever 3| a sleeve is formed in which a pin 36 is slidably mounted, the pin being normally urged through the sleeve against the 1 disc 32 by a spring, not shown, so as to urge the wall end of the pin into one of the recesses 33 or 34 when the handle is rotated into such posi-- tion that the sleeve 35 will lie adjacent one of the said recesses. $0

In the lower part of the cabinet 10 the front wall It is provided with a horizontally hinged door 31 which is adapted to open inward, as shown, and when in fully opened position is adapted to have; its upper edge rest against the 2 wall 38 of the cabinet. Near the bottom of the rear wall 38 an opening 39 is formedv and provided with a peripheral flange 4|]. A bag ll, of

the type usually used with vacuum cleaners,

' whose opening is at its lower end, is adapted to Q out of doors, and the .dust freed therefrom is 0 sucked down by the fan 29 through the screen 12 and into the bag 38. Whenit is desired 'to use the device as a fan for cooling purposes, the handle 3| is rotated through 180 degrees, after first pulling the pin 36 out of the recesses 34, and in its new position the pin 36 is permitted to enter the recess 35. Thus,,the frame 24 has likewise been rotated through-the same arc, and the fan 29 now takes the position shown in brokenlines in Figure? and acts as a blower, forcing air up from the bottom of the cabinet through the screen l2 and out of the porous openings l6 and l1 and of the door I 5. When using the device as a fan the door 31 is pushed open into the 'position shown in broken lines in Figure 2, so that I it acts as a balls to guide theincoming air outward toward the fan. When the cabinet is not being used as a suction apparatus, the bag 4| may be detached and kept in the bottom of the cabinet or in any other suitable place, so that the cabinet will have an attractive and ornamenta-l appearance and be of use as-an article of mounted on the opposite wall of the cabinet and having a bore therethrough in axial alignment with said motor shaft, a second shaft rotatably mounted in said bore, one end of said second shaft extending toward said motor shaft and the other end, extending through said housing and said opposite wall to the outside of the latter, a

frame having an opening through one side thereof and a socket in the other side thereof in axial alignment with said frame opening, said motor shaft passing through said frame opening and having its end registering in said socket. a sleeve on said frame also in said axial alignment, said one end of said second shaft being locked in said sleeve, a fan shaft extending through said frame at right angles to said motor shaft, said fan shaft having a fan on its outer end and having a bevel gear on its end within said frame, a bevel gear on said motor shaft within said frame in mesh with said first-named bevel gear, a handle on the said end of said second shaft which extends through said opposite wall, said frame and said fan shaft and fan being rotatable about said motor shaft as an axis by rotation of said handle.

2. A; device of the class described comprising a cabinet having an opening in its front wall near the top, a horizontal screen mounted within the cabinet near the base of said opening, a motor mounted below said screen and having its shaft extending horizontally therefrom, a housing mounted on the opposite wall of the cabinet and having a bore therethrough in axial alignment with said motor shaft, a second shaft rotatably mounted in said bore, one end of said second shaft extending toward said motor shaft and the other end extending through said housing and said opposite wall to the outside of the latter, a frame having an opening through one side thereof and a socket inthe other side thereof in axial alignmm with said frame opening, said motor shaft passing through'said frame opening and having its end registering in said socket, a sleeve on said frame also in said axial alignment, said one end of said second shaft being locked in said sleeve, a fan shaft extending through said frame at right angles to said motor shaft said fan shaft having a fan on its outer end and having a bevel gear on its end within said frame, a bevel gear on said motor shaft within said frame in mesh with said first-named bevel gear, a handle on the said .end of said second shaft which extends through said opposite wall, said frame and said fan shaft and fan being rotatable about said motor shaft as an axis by rotation of said handle, and means for releasably locking said handle selectively in diametrically opposed positions one vertically above the other, said fan when in its upper position functioning as a suction fan and in said lower position as a blower fan.
